Angular distributions in the radiative decays of the ${}^3{D}_3$ state of charmonium originating from polarized $\bar{p}p$ collisions

Cheuk-Ping Wong, Alex W. K. Mok, Wai-Yu Sit

Using the helicity formalism, we calculate the combined angular distribution function of the two gamma photons (${\gamma }_1$ and ${\gamma }_2$) and the electron ($e^{-}$) in the triple cascade proc…
